The pith

SHARP at the ELT can map stellar population gradients out to 2Re in most massive quiescent galaxies at z < 2.5 with 20-hour exposures.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper conducts a feasibility study for the proposed SHARP/VESPER integral field unit on the Extremely Large Telescope to obtain spatially resolved measurements of stellar age, metallicity, and enrichment in passive galaxies at redshifts 1.5 to 3. It selects a sample of massive quiescent systems from the COSMOS-Web catalogue, models them as compact and extended galaxies, and runs simulations through the official SHARP exposure time calculator to determine the integration times needed for signal-to-noise ratios of 10-15 per resolution element. The results indicate that routine mapping to twice the effective radius becomes practical for the majority of such galaxies below redshift 2.5 in roughly 20 hours, while redshift 3 targets reach at least one effective radius in about 30 hours. This setup would also resolve the central kiloparsec at all considered redshifts, permitting direct checks on whether central mass buildup drives quenching.

Core claim

Using the COSMOS-Web catalogue to define a realistic population of massive quiescent galaxies at 1.5 < z < 3 and modeling representative compact and extended systems, simulations with the SHARP ETC show that exposure times of about 20 hours suffice to reach S/N = 10-15 per resolution element out to 2Re for the majority at z < 2.5, while 30 hours reach at least Re at z = 3. The 30 mas resolution enabled by MORFEO MCAO resolves the inner < 1 kpc at all redshifts, allowing direct tests of quenching mechanisms tied to central mass build-up, bulge growth, and structural transformation.

What carries the argument

Simulations with the official SHARP exposure time calculator applied to compact and extended galaxy models drawn from the COSMOS-Web catalogue.

If this is right

  • Stellar population gradients become measurable out to 2Re for most massive quiescent galaxies at z < 2.5 in integrations of about 20 hours.
  • At z = 3 the same measurements reach at least Re with about 30 hours of integration.
  • The inner < 1 kpc region is resolved at all redshifts considered, enabling tests of quenching linked to central mass build-up.
  • Statistically meaningful, spatially resolved stellar population constraints become available during the epoch when stellar cores of these galaxies were assembled.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • Such maps could be combined with lower-redshift samples to trace how radial age and metallicity patterns evolve over cosmic time.
  • The ability to resolve central regions might distinguish between quenching scenarios that predict different inner stellar population signatures.
  • The exposure time estimates provide a benchmark that could guide observing strategies for similar IFU instruments on other large telescopes.

Load-bearing premise

The COSMOS-Web catalogue supplies a representative sample of massive quiescent galaxies at 1.5 < z < 3 and the chosen compact and extended structural models accurately capture the properties that determine required exposure times.

What would settle it

On-sky SHARP observations that require substantially more than 30 hours to reach S/N = 10-15 at z = 3 or fail to resolve structures inside 1 kpc as predicted by the models.

Understanding when and how massive quiescent galaxies (log(M*/Msun) > 10.5) assembled their stellar mass and quenched remains a central challenge in galaxy evolution. Spatially resolved stellar population measurements at z > 1.5 offer a uniquely powerful avenue to address this problem, as they can provide information on the radial variations in stellar age, metallicity, and enrichment histories in passive galaxies as they first emerge. In this work, we present a feasibility study quantifying the transformative capabilities of the proposed IFU SHARP/VESPER at the ELT for performing such radial mapping of stellar population gradients in passive galaxies at 1.5 < z < 3. Using the COSMOS-Web catalogue, we define a realistic population of massive quiescent systems at 1.5 < z < 3 and model representative compact and extended galaxies across this redshift range. Through detailed simulations with the official SHARP ETC, we derive the exposure times required to reach S/N = 10-15 per resolution element at key rest-frame optical wavelengths. Our results show that SHARP will routinely measure stellar population gradients out to 2Re for the majority of the population at z < 2.5 with integrations of about 20h, and that will reach at least Re in about 30h at z = 3. Thanks to MORFEO's MCAO and to its spatial resolution of 30mas SHARP/VESPER will also resolve the inner < 1kpc at all redshifts considered, enabling for the first time, direct tests of quenching mechanisms linked to central mass build-up, bulge growth, and structural transformation. These findings demonstrate that SHARP/VESPER will open an entirely new observational window on the early evolution of massive quiescent galaxies, providing, for the first time, statistically meaningful, spatially resolved stellar population constraints during the epoch when their stellar cores were assembled.

Referee Report

1 major / 1 minor

Summary. The manuscript is a feasibility study for the proposed SHARP/VESPER IFU on the ELT, using the COSMOS-Web catalogue to select massive quiescent galaxies at 1.5 < z < 3, modeling representative compact and extended systems, and running the official SHARP ETC to compute exposure times for S/N = 10-15 per resolution element at rest-frame optical wavelengths. It concludes that ~20 h integrations enable stellar population gradient measurements out to 2Re for the majority of the population at z < 2.5, while ~30 h reach at least Re at z = 3, with the MCAO resolution also resolving the inner <1 kpc at all redshifts.

Significance. If the exposure-time projections hold, the result would be significant because it quantifies how SHARP/VESPER can deliver the first statistically meaningful, spatially resolved stellar population constraints on massive quiescent galaxies during the epoch of core assembly, directly testing quenching mechanisms tied to central mass build-up and structural transformation. The use of an external catalog for sample definition and the official ETC for forward modeling are strengths that make the projections more reproducible.

major comments (1)
  1. [Abstract (sample definition and modeling paragraph)] Abstract (sample definition and modeling paragraph): the headline exposure times (20 h to 2Re at z < 2.5; 30 h to Re at z = 3) are obtained by feeding COSMOS-Web-derived compact/extended structural models into the SHARP ETC and requiring S/N = 10-15 per resolution element. No sensitivity analysis to plausible variations in Re, Sersic index, or surface-brightness profile is presented; any systematic offset toward lower surface brightness would increase the quoted times, making this assumption load-bearing for the central claim.
minor comments (1)
  1. Clarify in the methods section the precise quantitative criteria used to define the 'representative compact and extended' models (e.g., ranges in Re, n, and magnitude) so that readers can assess how the chosen parameters map onto the COSMOS-Web parent sample.

  1. Referee: [Abstract (sample definition and modeling paragraph)] Abstract (sample definition and modeling paragraph): the headline exposure times (20 h to 2Re at z < 2.5; 30 h to Re at z = 3) are obtained by feeding COSMOS-Web-derived compact/extended structural models into the SHARP ETC and requiring S/N = 10-15 per resolution element. No sensitivity analysis to plausible variations in Re, Sersic index, or surface-brightness profile is presented; any systematic offset toward lower surface brightness would increase the quoted times, making this assumption load-bearing for the central claim.

    Authors: We agree that this is a valid point and that the headline exposure times rest on the adopted structural parameters. Our analysis employs representative compact and extended models drawn directly from the COSMOS-Web catalogue to reflect the observed population, but we did not explore variations in Re, Sersic index or surface-brightness profile. In the revised manuscript we will add a dedicated sensitivity analysis (new subsection or appendix) that perturbs these parameters across the observed ranges at 1.5 < z < 3 and quantifies the resulting changes in required integration time. This will demonstrate the robustness of the quoted 20 h and 30 h figures. revision: yes

full rationale

The paper's central claims are exposure-time estimates obtained by selecting galaxies from the independent COSMOS-Web catalog, adopting representative structural models, and feeding them into the official SHARP ETC to compute required integrations for target S/N. No equations, parameters, or results are defined in terms of the output quantities themselves, no self-citations underpin the load-bearing steps, and no fitted inputs are relabeled as predictions. The derivation chain is therefore self-contained against external benchmarks.

Axiom & Free-Parameter Ledger
